The inhibitory effects of a novel chondroitin sulfate compound on lipopolysaccharide (LPS)- and acidosis-induced neuronal dysfunctions were examined. Cell viabilities in cultured neurons and/or astrocyte-rich cerebellar granule cells were measured by the calcein-AM method. Ten and 20 μg, as a final dosage, of LPS damaged less than 20% cells during a-2 h incubation. More than 5000 ng/ml of chondroitin sulphate-dipalmitoylphosphatidylethanolamine (CS-PE), but not chondroitin sulfate (CS) treatment, significantly inhibited such damage. Twenty μg of LPS damaged more than 40% cells during 24 h incubation, and these cell damages were significantly inhibited by less than 1000 ng/ml of CS-PE. Moreover, treatments with between 5 and 500 ng/ml CS-PE, but not CS, significantly reduced the number of acidosis-damaged cells in a dose-dependent manner. The current results indicate that modulator(s) of ECM and its derivative containing covalently linked dipalmitoylphosphatidylethanolamine show neuroprotective effects under conditions of brain inflammation.
